ABSTRACT:
Milking method and apparatus in which a diaphragm (8,29,39) interposed between a chamber (12,30,34) through which pulsation vacuum is applied to the outer cavity of a set of teat cups through a valve (11,6a, 7a, 33) and a further chamber (9) which is connected to the inner milking cavity of the teat cups so that the vacuum in the outer chamber is controlled by the valve (11,6a, 7a, 33) so as not to exceed and preferably to be equal to the vacuum in the milking cavity of the teat cup. The apparatus is provided in the milking machine claw and may be associated with one or two pulsators in that claw. Further valves (8,10a) prevent back flow from the claw to the teat cups.
